Java Proxy as Sender - with variable attributes

Hi Guys,

I am wondering how I could implement a generic XI Java proxy...

My goal is to specify the sender (service, ns, <b>interface</b> ...) dynamically and assign the corresponding payload directly to the proxy.

Unfortuantely I only find methods for configuring the receiver in the MesseageSepcifier interface - and not the sender. with <i>setPayload</i> I should be able to set any payload I guess.

Do I really need to use a WS client in order to dynamically set the sender or is there another way?

Thx in advance!

Helge
